How to scale analog in/out for compactlogix?

I have a project that is using a compactlogix 1769-if4,1769-of4c1 cards. I am using rslogix 5k v15.02. I do not have the function block editor pack. Currently the analog input cards are set for 0-10vdc in raw/proportional, the raw data reads 0@0vdc, 32117@10vdc input, while the analog output reads 12ma@0vdc input, and 20ma@ 10vdc. To get a 4ma ouput I have to write in -32000 to ouput. I have read all the post from search. But I just can't seem to wrap my mind around this. Any help is appreciated.


input raw data output ma raw data
0vdc 12ma 0
10vdc 20ma 32117

From the Help File in Logix 5000 for the 1769 Series analog output modules, including 1769-OF4CI:

 Output modules minimum and maximum values are detailed in the Min/Max Values table.

 

 Min/Max Values

 Output Range Field    Raw Proportional    Engineering Unit    Scaled for PID    Percent

 0…20 mA    -32,767…29,646    0…20,000    0…16,383    0…10,000

 4…20 mA    -29,822…29,085    4000…20,000    0…16,383    0…10,000

 0…10V    -29,788…29,788    0…10,000    0…16,383    0…10,000

 -10…10V    -31,207…31,207    -10,000…10,000    0…16,383    -10,000…10,000

 0…5V    -27,068…29,918    0…5000    0…16,383    0…10,000

 1…5V    -25,869…29,318    1000…5000    0…16,383    0…10,000

Anyone?

You are doing some strange things and I can't seem to see what you are trying to acheive.
The input being in int format is being copied to a real and then copied back to an output which is in int format.
This will never work and will give you some very strange values.
Set up some test rungs of code with dummy words and try it.

This is a project handed to me after two different integrators firms, failed. I have only started to debug and change the code. I have started with the paddlewheel first. As for the scale, I believe the problem lies in the generic analog module, instead of them updating it to the 4ch isolated output card. Which will allow me to manually set low point of scale.

There is no scale (SCL) instruction in RSLogix 5000 as far as I know so you have to make one. There is an example in the Rockwell Knowledge Base that should help you out. I don't have the Knowledge Base article number handy but it wasn't that hard to find as I recall. Hope this helps...

The first problem is in the copy command of an int to a real.
The copy is a byte to byte image command, NOT a copy of the value.
Why do you need the value in a real?
